IDEA 1

TARTAR REMOVAL SYSTEM:“Bacto-Gum”

Goal: To design a bacteria to remove tartar from teeth to prevent oral diseases and assist in oral hygiene.

Design: 1. Insert a gene into a bacterial plasmid that

causes bacteria to consume tartar. 2. Contain bacteria in a capsule with food to

keep them alive.3. Deliver to the consumer in chewing gum

form.

IDEA 1 - Method

The removal of tartar will improve oral hygiene and cleanliness which is key to overall health of the bodySome diseases have symptoms which affect the

mouth

Will serve as a vital product in preventing tooth decay and gum diseases (oral cancer, gingivitis, etc.)

The act of chewing causes secretion of saliva

IDEA 1 - Importance

Over all improvement in oral hygieneSupplement to brushing, flossing, using mouthwash, etc.

Reduce dental costs Many do not have insurance which covers dental careInexpensive enough to be marketed to impoverished

countries

Make oral hygiene products easily accessibleIs safe enough to be sold at retail storesDoes not require a prescription

Will allow for aesthetically pleasing teeth

IDEA 1 - Impact

Currently, the only way to remove tartar is to go to a dentist and have them use professional tools.

Scaling/Root Planing (using a pointed instrument to remove encrusted material from the root surfaces of the teeth)

Debridement (removal of plaque and tartar using an ultrasonic device)

Surgery

IDEA 1 - Competition

IDEA 1 – Known & UnknownKnown

Some types of bacteria reside in the mouth

Certain levels of acidity are bad for the bacteria

Tartar and plaque are created by both food and bacterial by products

Unknown

Reaction of the general public to bacterial cleaning methods.

Whether bacteria will consume anything else in the mouth

How bacterial will react to salivary enzymes

IDEA 2- Super-Rice

To genetically engineer rice into a special ‘super-rice’ rich in

amino acids

ImportanceRice is an important staple in third world

countries

Rich in protein, AND relatively cheap compared to other options; poor people benefit

Good alternative for people like vegetarians

Eliminates a percentage of meat associated cardiac health risks

ImpactHunger and malnutrition are common to

people in third world countries

Successful project = improved standard of living for such people

Another healthy option for Vegans and Vegetarians.

If tasty enough, could become a popular choice

CompetitionGenetic engineering is common in today’s

world- lots of projects around

Golden Rice – Vitamin A producing rice

Soy- good but not so popular in third world

‘Knowns Vs Unknowns’Knowns/Facts/Approach:

Rice contains at max 10% protein only

Lacks lysine, threonine, cysteine, and histidine for starters.

Approach: use of engineered Recombinant DNA to produce these and more amino acids in rice

‘Knowns vs Unknowns’Unknowns & Difficulties:

Genetic modification could disrupt genes having to do with reproduction- can only be verified if tested and grown

Super-rice taste

State approval for genetically modified food

Environmental opposition

Skepticism from target population

Costs

Environmental Opposition

IDEA 3Clean Clay Consumption

Removing toxins in clay to benefit the health of people practicing geophagy using a method

of bacterial filtration.

Methods

Settling tank

Filtration

Importance

Clay contains many mineralsReducing the risks of consuming clayProtecting health: reducing toxinsIncreased stores of clay able to feed people

Impact

Pregnant women consuming clay in rituals.People who eat clay for potential health

benefits. Third world countries who cannot afford most

food options.

Competition

similar technologies but not really a direct competition

bacteria removing toxins from water

Known/UnknownKnown: Clay is mineral richLead, arsenic, and chalk have negative effects on the

human body

Unknown:Costs? (clean price vs. current price)Specific type of bacteria (engineered or already

existing?)Bacterial waste products/waste removal?Able to remove enough toxins to make it safe?
